S3 snapshot repositories not working after upgrade from 1.7 to 2.3

Elastic Stack Elasticsearch
1

We have several snapshot repositories, created on a 1.7 cluster, that have their type property set to "S3". We also have several with type "s3". It seems that for a time elasticsearch accepted both "S3" and "s3" as a type, but now only accepts "s3".

When we upgraded to 2.3, on startup we get errors like the following for each of the "S3" repos:

[2016-07-23 05:19:42,914][WARN ][repositories             ] [snip] failed to create repository [S3][snip]

Is it possible to change the type property on a repo?
